A wide–band square–law circuit element
1955 Edition, Volume 2, April 1, 1955 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A square-law circuit element with operating frequency range from zero into the vhf region is described. Its dynamic range and accuracy capabilities vary with the particular conditions under which it is operated; accuracies within less than one per cent of full...

A wide-band square-waveguide array polarizer
1973 Edition, Volume 21, May 1, 1973 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A stepped-septum polarizer has been designed that is capable of at least 26 dB of isolation over a 20 percent frequency band. The three-port device may be used to excite high purity left or right circular, as well as tilted linear polarizations in a phased array of...

A wide-band square-law computing amplifier
1954 Edition, Volume EC-3, June 1, 1954 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Wide-hand computing amplifiers capable of accurately and continuously yielding output signals with amplitudes proportional to the mathematical square of their input amplitudes have been developed. These computers are designed to be inserted in signal channels in much the same manner...

A Wide-Band Square-Wave Generator
1941 Edition, Volume 60, June 1, 1941 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A square-wave generator is described which covers a very wide frequency range, is compact, self-contained, and adaptable to many other uses besides the investigation of transient response. The instrument uses a positive-bias type multivibrator. The operation of...

Dual polarization X-band square horn antenna
2016 Edition, October 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Nowadays, the antenna started to evolve along with the needs of the application of the antenna, including the horn antenna. Several types of antennas ever made using only one polarization with a rectangular shape that is applied to the S-band and C-band frequency and the...

A wide-band square slot antenna for high-temperature applications
2013 Edition, July 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A square slot antenna for harsh environment applications is proposed in this paper for its merits of wide bandwidth and survivability at high temperatures. This slot antenna is fed by a coplanar waveguide (CPW), and the wide bandwidth is realized by loading...

SRR incorporation for dual-band square patch antenna
2015 Edition, September 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper deals with the development of dual-band antenna by incorporating an array of SRR with wires into a single band of conventional microstrip square patch antenna. The proposed antenna is intended to work at 2 frequency bands for GPS (Global Positioning...

Receiver Integration for Mid-Band Square Kilometer Array Demonstrator Applications
2010 Edition, October 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Abstract- The international radio-astronomy community is proposing to build a telescope of unprecedented size in order to allow observation of the farthest reaches of space. This telescope is known as the Square Kilometre Array (SKA), and will be built in one of two...

A 3D Printed Aluminum Alloy K-Band Square Stepped Doubled Ridged Horn Antenna
2018 Edition, March 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We proposed a 3D printed K-band square stepped double ridged horn antenna in this paper. It is printed by the selective laser melting (SLM) technology using aluminum alloy. It features impedance bandwidth across the K-band, the in-band gain> 12 dBi with the...
